Hello everyone. i have always used mastercam until i switched jobs. know need to learn gibbs. have been manual programming so far but to make things worse i left a disc in the drive when i turned off the fadal and windows will not boot up any more this must be a common problem with every one it was so easy to do thank you in advance BIG JOHN

BJ--
If you still have the disk in A drive, remove it. The bootup sequence is set to look at the A drive first for the operating system then look to C drive if it doesn't find it.
Leaving a disk in the drive during power down should not have cause any problems for boot up. (Unless you leave the disk in the A drive during boot up).

not for sure what happened. when you turn the switch from cnc to pc it says something about a boot disc for windows. i will be more specific on my next post thank you BIG JOHN
